摘要

Herein we describe the synthesis and spectroscopic (infrared and UV-vis) analysis of [Cu-II(dohpn)(L)](n+) (dohpn = imineoximic tetraazarnacrocyclic ligand 2,3,9, 10-tetramethyl-1,4,8,11-tetraazaundecane-1,3,8,10-tetraen-11-ol-1-olate) and L = SCN-, I-, Cl- (n = 0) and 4-aminopyridine (ampy), 4,4'-bipyridine (bipy), imidazole (im), 2-aminopyrazine (ampz) and water (n = 1+). The following order of the Jahn-Teller stabilization energy (cm(-1)) was observed: I-(6452) < Cl-(6477) < NCS-(6494) < ampy(6562) < im(6614) < bipy(6685) < ampz(6739) < H2O(7813) and the energy of the crystal field transition was correlated with the tetragonal distortion in the structures.
